Canal effect figure shows an anchored barge that extends across a canal by distance d = 30m and into the water by distance b = 12m. The canal has a width D = 55m, & water depth H = 14m, and a uniform water-flow speed vi = 1.5m/s. Assume that the flow around the barge is uniform. As the water passes the bow, the water level undergoes a dramatic dip known as the canal effect. If the dip has depth h = 0.80m, what is the water speed alongside the boat through the vertical cross sections at
(a) Point a and
(b) Point b? The erosion due to the speed increase is a common concern to hydraulicengineers.
Water is in a 0.05 m^3 piston-cylinder assembly at 1 MPa, 220 C and the piston is resting on stops. Heat is added until the pressure doubles. At this point the piston movies until the volume increases by 50%.

The Prony brake shown in Figure 2 is commonly used in torque measurement. The rope is wound round the brake drum mounted onto the shaft. One end of the rope carries a dead load of weight W and the other end is attached to a spring balance
Water flowing through a 10-cm-diameter water pipe at a rate of 0.1 m3/s. Now a diffuser with an outlet diameter of 20 cm is bolted to the pipe in order to slow down water. The inlet side of the pipe is part of a continuous piping system (so that th..
A closed system consisting of 8.25 lb of a gas undergoes a process during which the relation between pressure and volume is pV^n = constant. The process begins with p1 = 18 lbf/in^2 , v1 = 1.25 ft^3 /lb and ends with p2 = 53 lbf/in^2 , v2 = 0.5 ft^3 ..
Two round, 3cm diameter bars are made of SAE 1030HR (hot-rolled) steel but are different lengths (15 cm and 60 cm, respectively). Compare the load supporting capability of the three bars if they are loaded in compression and the ends are assumed to b..
